> Subject: [PATCH v3] app/testpmd: perform SW IP checksum for GRO/GSO
> packets
>
> The GRO/GSO library doesn't re-calculate checksums for
> merged/fragmented packets. If users want the packets to have correct IP
> checksums, they should select HW IP checksum calculation for the port which
> the packets are transmitted to. But if the port doesn't support HW IP
> checksum, users may perform a SW IP checksum. This patch add the code
> about it.
